I like that you've cropped this into a square image centralising the fox as opposed to working with the rule of thirds. In this instance it works very well drawing attention to the subject straight away. You've also captured light reflecting in the eyes preventing the fox from looking dead/static.
The focus is on the eyes with everything else slightly out but still recognisable, this works really well in again drawing attention to the subject and its eyes.
The colours in the shot are beautiful, making it seem like you as the viewer are actually there looking at the fox yourself. You've really captured life in this shot!
